  • There are dependent fields that become queryable based the value from the source field.  For example, if you query against po-method=email, then po-email can be added as an additional query criteria.  Please see fields with Yes*.
  • For large data set and for performance optimization, you should always limit your result with some GET criteria.
  • PO changes do not always increment the version number. See Fields that Cause a Purchase Order Revision for more info..  The updated-at field can always be used to determine whether any changes have been made.
